VELOSIT® WS 805
Swellable thermoplastic gasket for segmental structures
Product Description
VELOSIT WS 805 is a swellable gasket manufactured from a blend of proprietary thermoplastics and swelling agents compounded to produce a re-swellable seal of unique swelling ability. VELOSIT WS 805 is used to seal joints between pre-cast segments.
VELOSIT WS 805 is the result of many years in the field testing and research. VELOSIT WS 805 is used to seal joints between pre-cast segments.
Typical Applications
- Sealing between pre-cast segments
- Sealing between potable water pipes
- Sealing sewage & wastewater pipes
- Waterproofing of wall/slab joints
Features
- Profile includes 2 protrusions to form double parallel compressible sealing lines
- 450% swelling capacity; fully reversible for an unlimited numberof cycles
- High water retention means delayed shrinkage when dry
- Dimensionally stable; does not wash-out like Bentonite waterstops
- Delayed swelling; volume increase starts after approx. 2 weeks ofcontact with water allowing water curing of precast units and/orplacing of segments and pipes in wet conditions
- Swelling pressure resistant to 5 bars hydrostatic water pressuresup to 50 m acc. to EN 12390-8e
- Extremely flexible: easily bent to take the shape of concrete segment.
